What is an Ultrasound Scan?

This is an imaging procedure that uses high-frequency sound waves to create images of the inside of the body. The instrument used in the procedure is called an ultrasound probe is.

During the procedure, the image is displayed on a monitor.

Types of ultrasound scans

There three types of ultrasound scans and the type of ultrasound scan you have will be determined by the body part being scanned.

External ultrasound scan: The ultrasound probe is placed onto the skin and moved over the body part being examined. A gel is applied to the skin to allow easy flow of the probe and continuous contact between skin and probe. This scan is noninvasive and painless and the only thing you will feel will be a coolness from the gel being applied and the probe on your skin.

Internal ultrasound scan: You will be asked to lie on an examination table on your back or on your sides with your knees drawn up. The ultrasound probe with a sterile cover is gently inserted into the rectum or vagina and the images are transmitted to the monitor. This scan causes a little discomfort and if you feel any pain you should let your doctor know.

Endoscopic ultrasound scan: This scan uses an endoscope that has an ultrasound device and a light on the end. The endoscope is inserted through the mouth into your body to examine body parts such as the gullet or stomach. You will be asked to lie on your side as the endoscope is gently and carefully pushed down towards your stomach. Once inserted it is used to create images which are displayed on a monitor. You will be given a local anesthetic spray to numb the throat area and a sedative to keep you calm.

How do I prepare

In some cases, you may be required to follow certain instruction to help improve the clarity and quality of the produced images.

You may be instructed by the doctor to drink water and avoid going to the toilet until after the scan and to avoid eating for several hours before the scan.
